So curiously decorated a brute living just outside the civilisation of the Egyptians, Greeks, and Romans, was sure to attract notice, especially as they were brought into Europe by the African merchants. Aristotle appears to have been struck with the hog-like look of the head, and he called it by the name of Hog-Ape (_Chœropithecus_), and all writers, from the earliest to the latest, have contributed opinions founded on very doubtful facts, to the detriment of its character. All the iniquities, abominations, and scandals that have been coupled with the Gorilla, Chimpanzee, and Orang-utan, are linked on fourfold to the character of the ill-favoured Mandrill, and this is decided to be quite correct by the natives of the Gold Coast and the inland regions, where it lives a most dreaded and independent life. There is no doubt that the Mandrill is extremely brutal in its adult age, and that the males are ferocious and disgusting, there being no particular choice as regards ugliness and oddity of decoration between their faces and sterns, whose callosities are vast. But the young are not so, and probably the quieter tints of the female are associated with a gentler disposition. Both the young and the females have shorter muzzles than the adult males, and they have neither the great cheek-swellings nor the colouring of the face; in fact, it is only when the great eye teeth are being cut by the males, as evidences of its age and powers, that the irregular decoration begins to be noticed.
